我有一个标准的重置按钮的形式编码如下:
<input type="reset" class="button standard" value="Clear" />
问题是，所述表单是多阶段排序的，所以如果用户填写了一个阶段，然后稍后返回，当单击Clear按钮时，各个字段的“记住”值不会重置。
我在想，附加一个jQuery函数循环所有的字段和清除他们'手动'将做的技巧。我已经在使用jQuery的形式，但我只是刚刚赶上速度&所以我不知道如何做到这一点，除了单独引用每个字段的ID，这似乎不是很有效。
请TIA帮忙。

Paolo的回答没有考虑日期选择器，添加这个:
$form.find('input[type="date"]').val('');

这里刷新了复选框和选择:
$('#frm').find('input:text, input:password, input:file, textarea').val('');
$('#frm').find('input:radio, input:checkbox').attr("checked",false).checkboxradio("refresh");
$('#frm').find('select').val('').selectmenu('refresh');
A method I used on a fairly large form (50+ fields) was to just reload the form with AJAX, basically making a call back to the server and just returning the fields with their default values. This made is much easier than trying to grab each field with JS and then setting it to it's default value. It also allowed to me to keep the default values in one place--the server's code. On this site, there were also some different defaults depending on the settings for the account and therefore I didn't have to worry about sending these to JS. The only small issue I had to deal with were some suggest fields that required initialization after the AJAX call, but not a big deal.
清除表单有点棘手，不像看起来那么简单。
建议你使用jQuery表单插件，并使用它的clearForm或resetForm功能。 它能解决大部分的极端情况。
以下是我的解决方案，它也适用于新的html5输入类型:
/**
* removes all value attributes from input/textarea/select-fields the element with the given css-selector
* @param {string} ele css-selector of the element | #form_5
*/
function clear_form_elements(ele) {
$(ele).find(':input').each(function() {
switch (this.type) {
case 'checkbox':
case 'radio':
this.checked = false;
default:
$(this).val('');
break;
}
});
}
这对我有用，pyrotex回答没有“重置选择字段，取他的，在这里”我的编辑:
// Use a whitelist of fields to minimize unintended side effects.
$(':text, :password, :file', '#myFormId').val('');
// De-select any checkboxes, radios and drop-down menus
$(':input,select option', '#myFormId').removeAttr('checked').removeAttr('selected');
//this is for selecting the first entry of the select
$('select option:first', '#myFormId').attr('selected',true);
